Multiduty glazing strip



O. A. MALO MULTIDUTY GLAZING STRIP July 13, 1937.

Filed April 29, 1956 Patented July 13, 1937 UNITE STATES PATENT orrics 2,086,675 MULTIDUTY GLAZING STRIP Gray A. Malo, Chicago, 111'. Application April 29, 1936, Serial No. 77,050 10 Claims. (01. 20-56.4)

My invention relates to windows and more particularly to materials for the glazing of the same, and my main object is to provide a device for puttied glazing jobs in the nature of a strip which firmly secures the glass to the sash.

A further object of the invention is to so design the novel glazing strip that it reinforces and holds the putty in place at all points.

Another object of the invention is to so construct the glazing strip that it forms a guide and rest for the putty knife, enabling the putty to be fully and neatly laid.

An additional object of the invention is to design the novel glazing strip along lines of exlo treme simplicity, in order that it may be inexpensively manufactured and used with facility by any person desiring to re-putty or install new glass in a window.

With the above objects in view and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the ac companying drawing in which- Fig. 1 is an elevation of a corner of a window a sash showing the application of a novel glazing strip, the putty therefor being shown in part;

Fig. 2 is a front elevation of a portion of the strip.

Fig. 3 is an end view from the right hand side of Fig. 2.

Fig. 4 is an enlarged section on the line 4-4 of Fig. 1; and

Fig. 5 is a view similar to Fig. 4, showing the application of a putty knife to the glazing strip. It is a familiar fact that window glazing jobs done with putty rarely remain tight as time goes on, the principal reason being that the putty cannot withstand the vibrations of the sash and atmospheric changes. The putty and a series of small tacks or barbs are usually depended upon to hold the glass in place until the putty sets or hardens. However, the putty may later crack or recede from the glass, so that the latter is insufliciently secured and therefore loose, even in some cases to the extent of falling out or breakingfrom a shock or draft. Also where this condition exists, the cracks between the putty and the glass permit water, moisture or frost to settle in the sash with the effects ofloosening the putty or rotting the sash. I have therefore developed the novel glazing strip with the intention of eliminating the deficiencies related above, and providing an installation which is neat, firm, tight and permanent. In accordance with the foregoing, specific reference to the drawing indicates the members of a window sash at l0 and the glass therefor at H. As is the usual practice, the sash members have a backing surface iiia for the glass, and a ledge or shelf surface 501) in front of the glass for the application of the putty l2. The novel glazing strip is applicable in the region over the shelf and the puttying operation is combined with the installation of the strip.

The glazing strip is a length of zinc, copper, or other sheet metal which is not affected by water or moisture. The strip is approximately one-half inch wide and only so thick as tobe firm. It is of a nature to be manufactured in lengths of one or more feet, and cut to requirements of different-sized sashes. The strip is composed of a'main body section l3 which is continuous along its top portion, but divided periodically below the same. Thus, the body sec- ,tion. has downward'extensions l3a in the same plane and of relatively narrow dimensions. Between the sections I311 are sections lib and He, occurring in succession. With the body of the strip inclined as indicated in Fig. 3, the section I3b is in the nature of a backward bend having a practically horizontal position. The section is also a backward bend but to a lesser extent, being inclined to form a spread with the section [3a like the sides of an isosceles triangle. The

bottom of the section lSa is bent forward with a horizontal foot i3d, the latter having a final upward bend in the nature of a hook We. The section l3a also has a small perforation H3 in the center: and above this perforation the body of the strip has a rectangular opening i3g.

In the application of the novel glazing strip, a suitable length thereof is placed on theshelf lllb in the manner shown in Figs. 1 and 4, whereby to have the bends 13b meeting the glass H and the bends I30 resting on the shelf me. The strip is now secured by driving brads M through the perforations l3 in the sections 13a into the stock of the sash members. Then the putty is spread on the strip and pressed with a putty knife to force it through the openings in the strip and over the top of the same so as to completely fill the entire space behind the strip. By passing the putty knife along the top edge of the strip and the corner of the shelf liib the outer or frontal surface of the putty is finished in neat form and with a straight top edge.

In considering the function of the glazing strip and its formation, it may be generally assumed that the body of the strip forms'a metallic reinforcing core for the putty. With the strip nailed retentive value of the bends I3b. It is seen that I Likewise, the hook or otherwise deform the strip. The horizontal base portions I3d combine to form a flat heel to resist tendencies from window shock or vibration to swing the strip forward or away from the glass with the brad heads as a pivot and so weaken the the body of the strip and the bends I3b form an undercut lock for the rear portion of the putty. I 36 forms an anchoring lock for the forward portion of the putty as clearly understood from Fig. 4, so that those parts of the putty which mostly receive disl'odgingor' straining tendencies are firmly retained by the strip. Finally, the top edge of the strip forms a guide for the putty knife in the manner seen in Fig. 5 so that no particular skill is necessary to form a neat frontal surface or finish for the putty and a top edge which is straight and not visible from the inner side of the window. Incidentally, the outer portion of the putty forms a bond with the inner one 'by Way of the openings I39 and those formed by the bends I32) and I3d causing the putty to become inseparably locked to its metallic core.

In case a window pane secured by the reinforced putty mounting described above is to be replaced or re-puttied, the old putty mounting is I easily removed by prying it up along its course with a screw driver, chisel or other flat-pointed tool. I

It will be evident from the above description that the novel glazing strip performs a multiduty service in keeping with its title. Yet, the strip may be stamped in one piecefrom ribbon metal by suitable forms or dies and with very little loss or waste. It is noted that thehook I 3e is parallel with the body of the strip in order to release the end of a forming die. It is. easily conceivable that the strip may therefore be manufactured so inexpensively as to be conveniently purchasable by home owners, building agents, glazers and janitors having charge of general repairs.

While I have described the novel glazing strip 7 along specific lines, it will be understood that the same is capable of various minor changes and refinements without departing from its principle as represented in the appended claims, and I consider all such changes and refinements as coming within the scope and spirit of the same.
